In a small bowl, combine the olive oil, minced garlic, oregano, thyme, rosemary, red pepper flakes, black pepper, and sea salt. Stir well to blend the flavors.
Add balsamic vinegar and Parmesan cheese (if using), and mix thoroughly. Let the mixture sit for at least 10 minutes to allow the flavors to infuse.
Preheat your oven to 375°F (190°C). Slice the baguette or artisan loaf into thick slices. Arrange the slices on a baking sheet and brush them with olive oil or melted butter. Sprinkle with sea salt.
Bake for 8-10 minutes, or until the bread is warm and slightly crispy on the edges.
Pour the prepared olive oil dip into a shallow dish and garnish with fresh parsley. Serve immediately with warm bread slices for dipping.
Notes
Use high-quality ingredients for the best flavor. For variations, consider adding different herbs or spices to the dip.
